LAWN-TRIMMING ATTACHMENT.

clear, and exact description.

In the use of lawn mowers of thevusual formv of construction, it has proved in practical operation to be substantially impossiblev to outl the grass on the extreme edge of a plot, especially where such edge forms the border of a road, walk or the like; furthermore the pressing roller of a lawn mower .y when used atl the edge of a plotl'lattens the grass which is not cut, causing it to project' outward over. the edge, and' also presses or breaks down the turf or sod yin such almanner as to destroy thesymmet-ry and straight alinement' of the face of the border. Necessity has therefore arisen for theuse of other `implements fortrimming or edginglawns or grass plots, such other implements either requiring great care and precislon in their usa-with the resulting expenditure of con'- siderable time and labor, or being in form .and labor required, to cut olf all'grass prol devices.

complicated and hence more or less costly It is the purpose of my invention to provide a lawn trimming or edging attachment of novel form and desigmwhich may be detachably securedto a wheel of an ordinary lawn mower and when in positionmay be efficiently operated, with a minimum of time jecting outward over the edge or border of va grass plot, and to trim the face of the turf or sod in a uniform andksymmetrical manner. v

My device may be adjusted for' use and operated by an unskilled laborer, and is of slmple design and constructiomcapable of being manufactured at a lowcost. Reference is to be hadl tol the accompanyfication, 1n which similar characters of reference indicate fcorresponding parts in all thelview's.

In the form of my invention shown, the

trimming or edging at-tachment consists of a circular rim or ring 1 provided atA one edge with a radially. projecting flange?J thereon and preferably integral. therewith. The flange,l 2 is of desired depth and tapers to a cutting edge at its periphery. The att-ach- ,I

ment 1s secured-in position on a wheel of a ylawnmower A in the instance shown, by-

means of set screws 4 passing through holesv 5 in the'rim l and bearing tightly upon the lawn mower wheel 3. AIn practice, the cutting or edging attachments will be manufac-l tured in various sizes tofi-t lawn mower wheels 'of differing diameters, but as the size of lawn mower wheels is substantially uniform, only a limited range of sizes of the attachment will be required. The rim 1 is preferably made comparatively broad, in that the turf or sod at the edge of the grass plot may ,be held firmly in place during the cutting or edging operation.v

' From the foregoing description the operation of my trimming` or edging attachment readily secured in place when its use is desired, and theA mower being run along the edge of a' grass plot., as-for example at the edge of a walk B, the rim ofthe attachment presses rmly .on the turf adjacent the edge, the cutter flange extending downward at the edge ofthe plot, cutting off all outwardlypro]ect 1ng grass, and trimming the face of the border uniformly in *a straight and continuous line.

, It is characteristic of my invention that the cutter is in theform of a member projectiner from the body .of the wheel, so that it is the body of the wheel, and not the axle lor frame parts, thatis the sole -supporting The attachment may be means for the trimming cutter. Itis adv Vantageous to locate the trimming cutter outside the frame of the mower, yet at the inside of the' wheel, vand this I have provided for.

Having thus described my invent-ion, I

- claim as new and desire to secure by Letters Patent: E

1. The combination with a. ground Wheel of a lawn 1noWer,- of a ring-like body p'rovided at one edge with a cutting flange having one side vertical, and its vother side inclined, said body being of greater' Width than the tread of the Wheel and detachably mounted thereon with its flange at, the inner side of said Wheel and in vertical alinementtherewith whereby a port-ion of the band will project beyond the tread of-said Wheel to, form means for compressing the turf to' facilitate the cutting thereof.

2. A lawn trimming attachment for lawn mowers adapted to be secured upon a, ground Wheel of the mower, comprising a ring-,like body of greater Width than the tread of the wheel upon which it is to be used, and pro-- WILLIAM E. HILL. Witnesses JOHN RoMIzER, MINOR BEST.
